Add PlatformIO project for the ESP32-2432S028R that: - Reads ThermoPro BLE BBQ thermometers via NimBLE-Arduino - Exposes /api/health, /api/latest, and /api/settings HTTP endpoints - Serves a captive-portal setup UI and touch dashboard - Persists WiFi/BLE/settings in NVS via Preferences Builds cleanly with pio run.
